Just finished the upgrade to Clearos 7 which was prepared on a different hardware platform (to reduce the downtime of my shares used by the family). Everything is configured as a stand-alone server and works great but...

I do have a perfect network connection to the server and no connection issues. From this new server I can ping everything within the local domain 192.x.x.x but all external traffic to and from the new server is has become a problem after the hardware swap (which has a different NIC)

After moving the prepared harddisk to the destination hardware, I ofcourse had to adapt the network settings which I did via the graphical interface. After a reboot everything worked as expected, but I just found out that I lost the possibility to connect to the internet directly, which did work fine before with the other Hardware...

Can't see something strange and I did not update any network config manually,
